Specification

The Methyl ether, with the CAS registry number 115-10-6 and EINECS registry number 204-065-8, has the systematic name of dimethyl ether. And the molecular formula of this chemical is C₂H₆O. The simplest ether is a kind of colourless gas, and belongs to the following product categories: Organics; Ethers (Low Boiling point); Gas Cylinders; Synthetic Organic Chemistry. In addition, when combusted, dimethyl ether produces minimal NOx and CO, though HC and soot formation are significant.

The physical properties of Methyl ether are as following: (1)ACD/LogP: 0.02; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 0.022; (4)ACD/LogD (pH 7.4): 0.022; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 24.478; (8)ACD/KOC (pH 7.4): 24.478; (9)#H bond acceptors: 1; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 9.23 Å²; (13)Index of Refraction: 1.309; (14)Molar Refractivity: 13.06 cm³; (15)Molar Volume: 67.912 cm³; (16)Polarizability: 5.177×10^-24cm³; (17)Surface Tension: 14.012 dyne/cm; (18)Density: 0.678 g/cm³; (19)Enthalpy of Vaporization: 21.51 kJ/mol; (20)Vapour Pressure: 4784.153 mmHg at 25°C.

Preparation of Methyl ether: It can be prepared by converting hydrocarbons sourced from natural gas or coal via gasification to synthesis gas (syngas). Synthesis gas is then converted into methanol in the presence of catalyst (usually copper-based), with subsequent methanol dehydration in the presence of a different catalyst (for example, silica-alumina) resulting in the production of Methyl ether.

Uses of Methyl ether: It is a useful precursor to other organic compounds and an aerosol propellant. It is also used as fuel in household and industry. In addition, it can also be used as a refrigerant.

You should be cautious while dealing with this chemical. It is a kind of extremely flammable chemical. Therefore, you had better take the following instructions: Keep container in a well-ventilated place; Keep away from sources of ignition - No smoking; Take precautionary measures against static discharges.

You can still convert the following datas into molecular structure:
(1)SMILES: COC
(2)InChI: InChI=1/C2H6O/c1-3-2/h1-2H3
(3)InChIKey: LCGLNKUTAGEVQW-UHFFFAOYAU
